A small charge of +1.0 micro-Coulomb (µC) is constrained to move (frictionlessly) along the x-axis. There is also a charge of +1.0 µC fixed at x = 0, and another charge of +2.0 µC fixed at x = 1.0 m, both fixed charges also on the x-axis. (a) Where is the equilibrium position of the movable charge? (b) Is the equilibrium stable or unstable? Explain.
The force acting on a particle constrained to move in 1-dimension is given by: F= ax(b- cx?)

A 4-kg particle moves along the x-axis under the influence of a conservative force. The potential energy is given by U(x) = bx^3 , where b = 8.0 J/m^3 . What is the magnitude of the acceleration of the particle (in m/s2 ) when it is at the point x = 2 m?
Suppose a particle is constrained to move along the x-axis. There are two rings of contin- uous charge distributions (total charge each of Q) centered on the x-axis and on a plane perpendicular to it. One ring is located at x L and the other at x =-L. (a) Obtain an expression for the potential due to the ring charges as a function of z for all x-values in between a E(-L, L). Hint: you should be integrating something. b)...
